Abstract

In a pest control metal phosphide composition which is protected against moisture the individual particles or small particle groups of phosphide are coated with a water-repelling solid substance, e.g. a natural synthetic resin, rubber, stearing or hard wax preferably hard paraffin wax, and this substance has added thereto a substance which is capable of controllable physical and/or chemical modification and/or decomposition under predeterminable conditions, e.g. a substance which, when the metal phosphide is used, quickly changes almost completely and directly from the solid to the gaseous state such as ammonium p carbonate, ammonium bicarbonate, sodium bicarbonate or ammonium cyanide, the modification and/or decomposition of which results indirectly or directly in the production of capilliary apertures in the coating which apertures permit the access of water vapour to the phosphide particles. The metal phosphides may be an alkaline earth metal phosphide such as magnesium phosphide or an earth metal phosphide such as aluminium phosphide, and the particles of which are preferably of a size below 5 microns. The composition may be prepared by combining 90 to 99 parts of phosphide preferably in powder form and 10-1 parts of the organic coating substance to form a mixed product which is then admixed with 10 to 50% by weight calculated on the final product, of the substance capable of being modified and/or decomposed. In another method the metal phosphide, prepared by thermal methods, is coated as it cools to a temperature from 100 to 300 DEG C. with the organic coating substance, preferably in molten form, and thereafter is ground to the desired degree of fineness, the substance capable of modification and/or decomposition, is added to the ground product and the resulting mixture is then pressed to form shaped elements. Alternatively the ingredients all in the cold state and in finely divided form may be simultaneously mixed before being pressed.ALSO:In a pest control metal phosphide composition which is protected against moisture the individual particles or small particle groups of phosphide are coated with a water-repelling solid substance, e.g. a natural synthetic resin, rubber, stearin or hard wax preferably hard paraffin wax, and this substance has added thereto a substance which is capable of controllable physical and/or chemical modification and/or decomposition under predeterminable conditions, e.g. a substance which, when the metal phosphide is used, quickly changes almost completely and directly from the solid to the gaseous state such as ammonium carbonate, ammonium bicarbonate, sodium bicarbonate or ammonium cyanide, the modification and/or decomposition of which results indirectly or directly in the production of capilliary apertures in the coating which apertures permit the access of water vapour to the phosphide particles.
